Imported pneumatic expansion butterfly valve Imported expansion butterfly valve Robert brand

Imported pneumatic expansion butterfly valve
(Germany Robert brand)
Product Description
The unique design of Germany Robert’s imported pneumatic expansion butterfly valve uses gas pressure to make the valve seat move towards the The pipe valve disc is spread out so that the expansion butterfly valve can provide a steadily distributed pressure for sealing at any time. Because during the opening and closing of the expansion butterfly valve, the valve disc and the valve seat will only have instantaneous contact, resulting in a slight collision of the valve disc. On the contrary, for ordinary butterfly valves, the collision caused by the valve disc rubbing against the valve seat will reduce the performance and life of the valve. In fact, only a small amount of torque is required to open and close the expansion butterfly valve. This allows the use of smaller actuators, thus reducing the overall valve energy requirements.
